i think everyone is familiar to this but i wonder if someone has made his research to study it.
what i mean is the namubers that when the result of multiplying them together is the same as adding them:
for example:
2*2=2+2=4 (trivial, i know (-: ).

my question has someone prooved that the number of these pairs are finite or infinite in the real numbers?
